Hello,
I'm making a pre-amp that utilizes TDA7318 (yes its old) and an analog VU-meter (with driver board) along with an Arduino Mega as a controller and a Nextion TFT for display and input.
So far so good, however, the TDA7318 audio output is 4.5V whilst my Vu-meter (nakamichi branded) requires a line-level input. Therefore, a conversion is required between them. I'm just ignoring impedance difference (if any) since it's above my poor electronics knowledge.
Appreciate any help.
Thanks
